example, in the seas of Nova'Zembla.^ 
Former voyagers have chiefly described representatives of the genus Cirratulus. 
Thus Schmarda gives six species of this genus, all of which are littoral. Kinberg 
mentions six new examples of the family, besides referring to two of Schmarda’s. 
Grube found only a single Cirratulus amongst the Annelids of the Gazelle,” and none in 
Semper’s series from the Philippines. Marenzeller, again, has two from Southern Japan, 
besides an example of Grnbe’s genus Acrocirrus. 
While the Challencrer was at sea the late Prof. Dickie of Aberdeen had some 
O 
fragments of .Melohesia procured by the shi]3 at St. Paul’s Pocks sent him. These cal- 
careous masses were perforated by boring Mollusks, Annelids, and Sponges. Amongst 
the Annelids were fragments of Dodecaceria, a member of the present family, and well 
known all over the world as a borer in shells, calcareous rocks, and similar substances.

Habitat.— Fonad between tide-marks at Sea Point, near Cape Town. 
A form of considerable size, reaching about 90 mm. in length and 5 A mm. in 
breadth. Schmarda, who describes the animal from life, appears to have met wdth larger 
examples at Table Bay, for he gives the length at 200 mm., the breadth at 9 mm., and 
the length of the tentacles (branchise) at 1 5 mm. 
In external configuration the species approaches the British Cirratidus borealis (a 
form furnished with eyes) especially as regards the blunt snout, the great size of the 
branchiae, the distinctness of the body-segments, and the number of the hooks in the 
inferior division of the foot. The colour of the body in life is stated by Schmarda to be 
dark violet while the branchiae are orange. 
As in the British form the long flattened simple bristles anteriorly show well- 
marked serrations along the margin (PI. XXI Va. fig. 9), and many have minute wdnged 
stalks (probably Algae T) parasitic on them. The anterior hooks are less tinted, more 
slender and less distinctly curved than the dark brownish posterior ones (PI. XXIVa. 
fig. 10). 
In the intestinal canal is muddy debris containing fragments of Crustacea, sponge- 
spicules, Diatoms, and other structures. 
The cuticle and the thick glandular hypoderm of this form do not materially diverge 
from the arrangement in Cirratidus cirratus. The circular muscular coat in the same
